And because React warnings in general only fire in development, it means that these warnings are never shown when building with Gatsby 😱 This is a trade-off. By opting out of server-side-rendering in dev, Gatsby is optimizing for a short feedback loop. Being able to quickly see the ...
Optimizations to stateless componentshave been promisedand I’m sure something will happen on that plan in one of the future versions of React. The Simplest Performance Trick in React Complex build optimizations aside,the crucial step in performance tuning for React applications is knowing when to ...
Gatsby is historically known as a static site generator enhanced with React Hydration. But starting with Gatsby 4, you can choose alternative rendering options in addition to static site generation (SSG) — on a per-page basis. This type of granular control allows you to optimize for performance...
Pre-Rendering allows you to speed up page loads for static content by rendering pages at build time instead of at runtime. Pre-rendering is enabled via the prerender config in react-router.config.ts and can be used in two ways based on the ssr config value:Alongside...
chunks that the browser can progressively render as it's received. This can provide a fast First Paint and First Contentful Paint as markup arrives to users faster. In React, streams being asynchronous inrenderToNodeStream()- compared to synchronous renderToString - means backpressure is handled ...
The first steps of using React Query is always to create aqueryClientand wrap the application in a<QueryClientProvider>. When doing server rendering, it's important to create thequeryClientinstanceinside of your app, in React state (an instance ref works fine too).This ensures that data is...
This means that by default, any JavaScript code that you run will block any other browser tasks from running, such as painting the screen. This is why it's especially important that JavaScript code be fast. However, in some cases, even the performance of the React reconciliation code isn't...
With the launch ofReactserver components in React 18,Layouts RFCis one of the most awaited feature updates in the Next.js platform that will enable support for single-page applications, nested layouts, and a new routing system. Layouts RFC supports improved data fetching, including parallel fetchi...
React.memo React.memo is a component level cache API in React, which can temporarily store rendered components, and when necessary, decide whether to update the rendering or obtain it directly from the cache to avoid unnecessary component rendering. And its' usage: const MyMemoedComponent = Reac...
Animation usually appeals to artists and studios looking to engage viewers with lively characters and scenes. Hence, they create figures that bounce, collide, and react in ways that feel real or entertaining. Beginners may wonder how to make motion real rather than stiff. On the other hand, pr...
